You can scrape by with that if you also make sure you don't have dracut-config-rescue installed, but you can find yourself struggling even with that, and so have to micromanage even further. Upgrade a kmod, watch /boot fill up, and find yourself in a bad place. If you only had it set to 200M, I'd reinstall now. If you had it set to 500M, you'd cope. jh
500 MB should be fine for the /boot partition. I believe that is the default with minimal installations on both CentOS 6 and 7. -- Paul Norton On Wed, Nov 16, 2016 at 8:49 AM, John Hodrien <J.H.Hodrien at leeds.ac.uk> wrote:> On Wed, 16 Nov 2016, Matt wrote: > > Can I just change yum.conf with the setting installonly_limit=2 to >> limit kernels installed too two? >> > > I really wouldn't.

A few years back we had a few machines running fedora, and at, was it 17? - they added preupgrade, they were building and stuffing a *lot* of stuff in /boot, and were recommending at least 500M. We just went to a 1G /boot by default. mark
